@imjasonh noticed output like this:

2023/03/31 17:10:58 error during command execution: 9 errors occurred:
	* failed to create a version from package python-3.12: 3.12.0_alpha6: Malformed version: 3.12.0_alpha6
	* failed to create a version from package openssh: 9.3_p1.  Error: Malformed version: 9.3_p1
	* package llvm-lld: update found newer version 16.0.0 compared with package.version in melange config
	* package py3.11-installer: update found newer version 0.7.0 compared with package.version in melange config
	* package libsm: update found newer version 1.2.4 compared with package.version in melange config
	* package clang-15: update found newer version 15.0.7 compared with package.version in melange config
	* package libpaper: update found newer version 2.0.10 compared with package.version in melange config
	* package py3-more-itertools: update found newer version 9.1.1 compared with package.version in melange config
	* package py3.10-installer: update found newer version 0.7.0 compared with package.version in melange config

There might be 2 underlying problems here:

1. The failed to create a version from package — this appears to be an error from hashicorp/go-version bubbling up when it shouldn't be.
2. We shouldn't have "newer updates available" be a concern during lint checks (except possibly as a warning)

@kaniini @rawlingsj @imjasonh Does this need our attention urgently? Or should we keep this on the back burner?
